SocialMiner Feeds - Invalid Feeds

Verify that the feed is one of the supported types. You can verify the RSS feed using a feed validator such as the W3C Feed Validation Service

If the site is not providing a valid Feed or is providing a version of RSS that is not supported by SocialMiner, you may be able to use a service such as Feed Burner to read the invalid feed and publish a reformatted/supported feed. Another feed manipulation service you may try is Yahoo Pipes.
